APPARATUS FOR EJ'ECTING FLUID MATTER.

T 0 all whom it may concern:

Be it known that I, HUBERT BEDDOES, a citizen of the United States, anda resident of the city and county of Philadelphia and State ofPennsylvania, have invented an Improvement in Apparatus for EjectingFluid Matter, of which the following is a specification.

Heretofore it has been customary to eject sewage and other fluid matterfrom tanks by air acting expansively, z'. e. at each op eration, thereis admitted to the tank that charge of air under pressure which actingexpansively will give a resulting pressure suificient to lift the liquidto the point of discharge.

It is the object of the present invention to accomplish the desiredobject by the use of less air, or of air under less pressure, and thisresult I accomplish by mingling with the air admitted to the tank aquantity of steam or other hot vapor or gaseous fluid under pressure.The high temperature of the steam, Vapor or gas, thus mixed with the airacts to raise the temperature of the air and thus increases itsexpansion. The air thus mingled with the steam, vapor or gas, retardscondensation and the effect produced is the result of the combinedaction of both the steam, vapor or gas, and air acting expansively onthe liquid.

By the addition of a small quantity of steam suflicient expansion may beobtained to eject the contents of the tank from a charge of air, which,without the steam, would be Wholly inadequate. When there is availablefor the purpose exhaust steam or hot gases exhausted from a gas engine,which would otherwise be wasted, a great saving may be eifected by theuse of the invention. My invention is not, however, limited to the useof exhaust steam, gases or vapors, but the steam, gas or vapor, usedmust have sufficient heat and pressure to raise the temperature of theair to a substantial extent.

The drawing shows a partly sectional side elevation of an apparatusembodying the invention.

a is any appliance to which the pressure is applied at intervals; asshown it is a forcing tank or receptacle which receives sewage through asupply pipe at, and from which the sewage is discharged through adischarge-pipe M.

d is a fluid pressure pipe which leads to Specification of LettersPatent.

the upper part of the receptacle a, as through the mixing chamber Z)opening into the top a of the receptacle.

(i is the pressure-main from which the pipe (Z leads, the communicationbetween the pipe (Z and the main (Z being controlled by the valvemechanism 0.

0 is a pipe leading from an exhaust-pipe or any other source of supply,by which steam or other hot vapor or gaseous fluid above atmosphericpressure is supplied to the mixing chamber 7) and receptacle a. The pipe0 is provioed with a hand valve 0 f is a small bell in the upper part ofthe appliance a from which an air-pipe f leads to the valve-mechanism 0.

7c is a valve in the pipe 0 which is controlled through an air-pipe 70from the valvemechanism c. As shown this valve is opened by a smallpressure-motor 70 operated by the pressure admitted through the pipe 76and is closed by a spring 76 when the pressure in the pipe 70 isrelieved.

When the sewage, or other liquid, rises in the tank a beyond the end ofthe bell f, air is forced through the pipe f to the valvemechanism, andputs that mechanism in operation to admit air under pressure to thepipes (Z and 70. A small quantity of steam, vapor or gas, is thusadmitted to the chamber Z) and tank a with a charge of air. The air andsteam, vapor or gas, thus admitted act expansively upon the surface ofthe liquid contained in the receptacle a and drive the liquid outthrough the discharge pipe (4 As the temperature of the air is raised bythe steam, vapor or gas, its expansion is increased, and at the sametime the mingling of the air with the steam, vapor, or gas, retardscondensation, so that the expansive force is much greater than could beobtained by the action of steam or air alone; and the force required todischarge the contents of the receptacle (4 can be obtained with air atless pressure, when supplemented by a small volume of steam, than wouldotherwise be possible. hen exhaust steam, vapor or gas,-which wouldotherwise be wastedis used for the purpose, a substantial saving resultsin the operation of the apparatus.

The particular construction of the valvemechanism which controls theadmission of the air and steam is not material to the illvention. Anyform of mechanism may be employed which will operate to admit a changeof air to the pipe 03 and simultaneously open a valve in the pipe 0 Forthe purpose of illustration I have shown the valve-mechanism fullydescribed in Letters Patent No. 979,698, dated December 27th, 1910. Bythis mechanism, at each operation a main valve is momentarily opened toadmit a charge of air fram the main (Z to the air pipe (Z, and at thesame time a charge of air is admitted through branch pipes d (Z to thepipe 70. This acts on the motor k to open the valve is for an instantand admit the desired quantity of steam.

It is to be understood that where in the claims I speak of the pipe 0 asa steam pipe I mean to include such a pipe when used to supply any otherhot vapor or gaseous fluid for the purpose described.

What I claim is as follows:

1. In apparatus of the character described, the combination of a tank tocontain fluid matter having a discharge-pipe, an air-pressure-pipe and asteam-pipe leading to said tank, and valve-mechanism controlling saidsteam-pipe and air-pipe to control the admission of steam and airtogether to said tank.

2. In apparatus of the character described, the combination of a tank tocontain fluid matter having a discharge-pipe, an air-pressure-pipe and asteam-pipe leading to said tank, and valve-mechanism controlling saidsteam-pipe and air-pipe to control the admission of steam and airtogether to said tank and controlled by the conditions in said tank.

3. In apparatus of the character described, the combination of a tank tocontain fluid matter having a discharge-pipe, an airpressure-pipe and asteam-pipe leading to said tank, and valve-mechanism controlling saidsteam-pipe and air-pipe to control the 5. In apparatus of the characterdescribed,

the combination of a tank to contain fluid matter having adischarge-pipe, an air-pressure-pipe and a steam-pipe leading to saidtank, valve-mechanism controlling steam-pipe and air-pipe to control theadmission of steam and air together to said tank, an air-bell in saidtank, and an airpipe leading from said air-bell to the valvemechanismand controlling its operation.

6. In apparatus of the character described,

the combination of a tank to contain fluid matter having adischarge-pipe, an air-pressure-pipe leading to said tank, a steam-pipealso leading to said tank, a valve-device in said steampipe, an air-pipeleading to said valve-device in the steam-pipe and controlling it, andvalve-mechanism for controlling the admission of air to said air-pipeleading to the tank and to the air-pipe leading to the valve-device inthe steam-pipe.

In testimony of Which invention, I hereunto set my hand.
